yes, generally, we like kissing things!
coptogeek has described it well.
copts kiss the gospel in church when there are not too many (otherwise just the chanters and altar servers do) and ethiopians / eritreans kiss the gospel 3 times as the priest carries it around the church after the gospel reading.
so in the different oriental orthodox churches the kissing practices are slightly different, and usually (not always) men kiss only men in church and women kiss only women. everyone kisses the icons and the babies. as a general rule, when in doubt, kiss!
